Small Help with assignment

[dr_goose91]

Hey, I'm not sure if its against the rules asking for help with assignments and if it is then I'm sorry and you may delete this. I am nearly done with my assignment. I finished the hardest parts but I am stuck on two little bits.

The assignment is to make a image editing application. It has to be very basic. I did all the colour correction sections but I don't know how to crop the image or clear it without using a picture box. I have uploaded my assignment, if someone can have a look and tell me what I missed. Any help is greatly appreciated

Hi,

I didn't actually look at your source, but in terms of cropping, you might want to look at:

Bitmap sourceBmp = //Whatever
Bitmap croppedBmp = new Bitmap(cropWidth, cropHeight);
Graphics g = Graphics.FromImage(croppedBmp);

g.DrawImage(sourceBmp, -cropLeft, -cropTop, cropWidth, cropHeight);

g.Flush();
g.Dispose();

Where cropLeft and cropTop are the coordinates of the left and top crop region and cropWidth and cropHeight are the width and height of the crop region.

Oh, also I should remark: thanks for mentioning it was an assignment. You're free to ask for help here, but usually we want to see you have worked on it yourself and gotten stuck (sounds like your case).

Most typically, it's easiest for us to help you if you show us the relevant code sections that you are having trouble with directly in the message (you can enclose them with [code] and [/code] tags so that the formatting looks nice). Most posters (I think) will not take the time to open up attached code files to look at them.
